(6) to be installed rotatably but below the pinch lever (5) to form a working cam (7) and the upper side to form a locking jaw (8). In addition, the soft brake lever 9 and the reverse brake lever 10 for braking the disc hub 2 and the reel disc 3 are rotatable by the second pivot 11 and the spring 12. Resilient installation, but the spring 12 is elastically installed on the fixing piece 13 and the deck 1 formed in the brake lever (9), (10), and also the soft brake lever (9) and reverse brake lever (10) The brake bands 14 and 14 'are fixed to the tip of the brake, and the actuating protrusion 15 is formed on the reverse brake lever 10. Reference numeral 16 is a pinch roller, 17 is a capstan shaft, 18 is a tape.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
먼저, 도시된 제1도에 의하여 설명한다.First, a description will be given with reference to FIG. 1.
도시된 제1도는 테이프레코더내에 테이프(18)가 장착되어 정상플레이 상태를 나타낸 것으로 소프트브레이크레버(9)의 브레이크밴드(14)가 디스크허브(2)에 밀착하여 릴디스크(3)의 회전속도를 조절하고 있는 것인데, 이는 릴디스크(3)를 완전히 정지시키지는 아니하고 단지 릴디스크(3)의 회전속도를 늦추게하여 속도를 조절하는 것이다. 즉 소프트하게 릴디스크(3)를 제동하고 있는 것으로 그 이유는 제1도에서 도시된 릴디스크(3)는 서프라이릴디스크로서 이와 대응하는 테이크업 릴디스크의 회전에 의하여 서프라이릴디스크에서 테이크업 릴디스크로 테이프를 공급하여 주게되어 있는데 서프라이릴디스크의 회전속도가 관성력에 의하여 테이크업릴디스크의 회전속도 보다 빠를경우에는 주행중인 테이프(18)가 늘어지거나 처지게되어 텐션을 유지하지 못하게된다. 그러므로 테이프(18)에 기록된 신호를 양호하게 재생시키지 못하게되는 것이다.1 shows a normal play state in which the tape 18 is mounted in the tape recorder. The brake band 14 of the soft brake lever 9 adheres closely to the disc hub 2 so that the rotational speed of the reel disc 3 is maintained. This is to adjust the speed, which does not stop the reel disk (3) completely, but simply adjust the speed by slowing the rotational speed of the reel disk (3). That is, the reel disk 3 is softly braked. The reason for this is that the reel disk 3 shown in FIG. 1 is a supply reel disk, and the take-up reel disk is rotated by a take-up reel disk. The tape is supplied to the reel disk, but if the rotational speed of the sub-reel disk is faster than that of the take-up reel disk due to the inertia force, the running tape 18 is stretched or sag, and thus the tension cannot be maintained. . Therefore, the signal recorded on the tape 18 cannot be reproduced well.
그러므로 테이프(18)의 텐션이 유지되기 위해서는 언제나 테이크업릴디스크와 서프라이릴디스크의 회전속도가 알맞게 유지되어야 하는 것이다. 그러므로 소프트브레이크레버(9)의 브레이크밴드(14)는 릴디스크(3)의 디스크허브(3)에 밀착되어 릴디스크(3)의 회전속도를 조절하는 것이다. 그런데, 상기에서 디스크허브(3)에 소프트브레이크레버(9)의 브레이크밴드(14)가 밀착되기 위해서는 덱크(1)와 고정편(13)간에 탄력설치된 스프링(12)의 인장력에 의하여 고정편(13)이 당겨지고, 고정편(13)이 당겨짐에 따라 이와 일체로 고정설치된 소프트브레이크레버(9)와 역브레이크레버(10)가 제2회동축(11)을 중심으로 회동하면서 소프트브레이크레버(9)의 브레이크밴드(14)가 디스크허브(2)를 밀착하게 되는 것이다.Therefore, in order to maintain the tension of the tape 18, the rotational speeds of the take-up reel disk and the sub-reel disk should be properly maintained. Therefore, the brake band 14 of the soft brake lever 9 is in close contact with the disk hub 3 of the reel disk 3 to adjust the rotational speed of the reel disk 3. By the way, in order to be in close contact with the brake band 14 of the soft brake lever 9 to the disk hub 3, the fixing piece (by the tension of the spring 12 elastically installed between the deck 1 and the fixing piece 13) 13) is pulled out, the soft brake lever 9 and the reverse brake lever 10, which is fixedly installed therein as the fixing piece 13 is pulled, rotate about the second pivot 11, and the soft brake lever ( The brake band 14 of 9) is in close contact with the disc hub 2.
다음, 정상주행을 하다가 모우드변환을 하거나, 또는 정상주행을 정지시키기 위하여 릴디스크(3)를 정지시켜야 하는데 이와같은 작용효과를 얻기 위하여 즉, 릴디스크(3)를 정지시키기 위한 작동원리를 도시된 제2도에 의하여 설명한다.Next, the reel disk 3 should be stopped in order to perform the mode conversion or stop the normal driving while driving. In order to achieve such an effect, that is, the operation principle for stopping the reel disk 3 is illustrated. It demonstrates by FIG.
핀치레버(5)의 상방에 설치된 구동캠(4)을 구동시키면, 이때 구동캠(4)이 핀치레버(5)의 걸림턱(8)을 누르게되고, 걸림턱(8)이 눌러짐에 따라 핀치레버(5)는 제1회동축(6)을 중심으로 회동하게 된다. 이때 핀치레버(5)가 회동함에 따라 이의 하방에 형성된 작동캠(7)이 역브레이크레버(10)의 작동돌기(15)를 밀게되고 작동돌기(15)가 밀려짐에 따라 역브레이크레버(10)는 제2회동축(11)을 중심으로 회동하면서 상기 역브레이크레버(10)의 브레이크밴드(14')가 릴디스크(3)에 밀착되어 제동을 하게 되는 것이다. 그런데 상기 역브레이크레버(10)가 제2회동축(11)을 중심으로 회동할때 역브레이크(10)와 소프트브레이크레버(9)는 일체로 설치되어 있으므로 고정편(13)에 탄력설치시킨 스프링(12)의 텐션을 발생시키면서 상기 소프트브레이크레버(9)도 함께 회동하여 이에 고착된 브레이크밴드(14)가 디스크허브(2)로부터 이탈되는 것이다.When the driving cam 4 installed above the pinch lever 5 is driven, the driving cam 4 presses the locking jaw 8 of the pinch lever 5, and as the locking jaw 8 is pressed, The pinch lever 5 rotates about the first pivot 6. At this time, as the pinch lever 5 is rotated, the actuating cam 7 formed below it pushes the actuating protrusion 15 of the reverse brake lever 10 and the actuating protrusion 15 is pushed as the reverse brake lever 10 is pushed. ) Rotates about the second rotating shaft 11, the brake band 14 'of the reverse brake lever 10 is in close contact with the reel disk 3 to brake. However, since the reverse brake 10 and the soft brake lever 9 are integrally installed when the reverse brake lever 10 rotates about the second rotation shaft 11, the spring is elastically installed on the fixing piece 13. The soft brake lever 9 is also rotated together while generating the tension of (12) so that the brake band 14 fixed thereto is detached from the disc hub 2.
다음, 릴디스크(3)를 역브레이크레버(10)의 브레이크밴드(14')에 의하여 걸린 제동을 다시 풀기위해서는 상기의 구동캠(4)을 다시 구동시켜 누르고있던 핀치레버(5)의 걸림턱(8)에 누르고있던 힘을 제거한다.Next, in order to release the braking of the reel disk 3 by the brake band 14 'of the reverse brake lever 10, the locking jaw of the pinch lever 5, which is driven by pressing the driving cam 4 again, is pressed. Remove the force held by (8).
이때 상기에서 텐션을 발생시킨 스프링(12)의 인장력에 의하여 고정편(13)을 당기게되고 고정편(13)을 당김에 따라 이와 일체로 고정설치시킨 역브레이크레버(10)와 소프트브레이크레버(9)를 제2회동축(11)을 중심으로 회동시킨다. 이때 역브레이크레버(10)에 형성한 작동돌기(15)와 핀치레버(5)의 작동캠(7)이 접촉되어 있으므로 작동돌기(15)가 작동캠(7)을 역브레이크레버(10)가 회동하는 방향으로 밀게된다.At this time, the fixing brake 13 is pulled by the tension force of the spring 12 that generates the tension, and the reverse brake lever 10 and the soft brake lever 9 which are fixedly installed thereon as the fixing piece 13 is pulled out. ) Is rotated about the second rotating shaft (11). At this time, since the actuating protrusion 15 formed on the reverse brake lever 10 and the actuating cam 7 of the pinch lever 5 are in contact with each other, the actuating protrusion 15 causes the actuating cam 7 to actuate the actuating cam 7. Pushed in the direction of rotation.
따라서, 작동캠(7)과 일체로 형성된 핀치레버(5)를 다시 제1회동축(6)을 중심으로 역회동시켜 도시된 제1도와 같이 핀치레버(5)가 작동되기 전인 최초의 상태로 원상복귀시키면서, 역브레이크레버(10)에 고착시킨 브레이크밴드(14')는 릴디스크(3)로부터 이탈되어 릴디스크(3)의 제동을 풀게되는 것이다. 또한, 소프트브레이크레버(9)의 브레이크밴드(14)는 다시 디스크허브(2)에 밀착되어 최초 작동되기전의 상태로 원상 복귀된다.Accordingly, the pinch lever 5 integrally formed with the actuating cam 7 is rotated back about the first pivot shaft 6 to the initial state before the pinch lever 5 is operated as shown in FIG. The brake band 14 ′ fixed to the reverse brake lever 10 while being restored to the original state is released from the reel disk 3 to release the braking of the reel disk 3. In addition, the brake band 14 of the soft brake lever 9 is brought into close contact with the disk hub 2 and returned to its original state before being operated for the first time.
이와같이 본 고안은 핀치레버(5)에 작동캠(7)을 일체로 형성하여 간단한 구성으로 릴디스크(3)를 제동할 수 있도록 함으로써 신속한 브레이크 작동을 릴디스크(3)에 전달하고, 또한 정확한 작동을 갖게된다. 뿐만아니라 구성을 간소화함에 따른 원가상승의 원인을 방지하여 작업공수를 유리하게 하는 특징을 제공함에 있다.In this way, the present invention forms the actuating cam 7 integrally with the pinch lever 5 so that the reel disk 3 can be braked with a simple configuration, thereby delivering a quick brake operation to the reel disk 3, and also providing accurate operation. Will have In addition, it provides a feature to advantageously work maneuver by preventing the cause of cost increase by simplifying the configuration.
